Kicking things off as always is Crysis: Warhead, still one of the toughest games in our benchmark suite. Even three years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and for three years the answer was “no.” Dual-GPU halo cards can now play it at Enthusiast settings at high resolutions, but for everything else max settings are still beyond the grasp of a single card.

Crysis is often a bellwether for overall performance; if that’s the case here, then NVIDIA and the GTX 590 is not off to a good start at the all-important resolution of 2560x1600.

AMD gets some really good CrossFire scaling under Crysis, and as a result the 6990 has no problem taking the lead here. At a roughly 10% disadvantage it won’t make or break the game for NVIDIA, but given the similar prices they don’t want to lose too many games.

Meanwhile amongst NVIDIA’s own stable of cards, the stock GTX 590 ends up slightly underperforming the GTX 570 SLI. As we discussed in our look at theoretical numbers, the GTX 590’s advantage/disadvantage depends on what the game in question taxes the most. Crysis is normally shader and memory bandwidth heavy, which is why the GTX 590 never falls too far behind with its memory bandwidth advantage. EVGA’s mild overclock is enough to close the gap however, delivering identical performance. A further overclock can improve performance some more, but surprisingly not by all that much.

The minimum framerate ends up looking better for NVIDIA. The GTX 590 is still behind the 6990, but now it’s only by about 5%, while the EVGA GTX 590 squeezes past by all of .1 frame per second.

For me the gaming differences between AMD Nividia at this level would not get me to change allegiance. In my case I bought two EVGA classifieds but they may never see a game. I use them as low cost replacements to the Telsa cards. For Parallel processing I held off until we had powers of two ie 256 512 1024 cores. I did not like 240 432 480 alternatives. Just easier to work with powers of 2. The lower noise and lower power were big winners. Evan if the power supplies can handle them you still have to get the heat out of the room. My 4 nodes of 1024 cuda cores each are a pain to air condition in my den. I really love you gamers, you buy enough GPU's to keep the competition going and lowering the price for impressive computation power. Thanks all!

I thought you guys learned your lesson the last time you pitted a factory-overclocked reference nVidia card against a stock AMD card. If you're going to use an overclocked card in an article that's meant to establish the performance baseline for a series of graphics cards (as this one does for the GTX 590 series), then you really should do at least one of:

1. Downclock the overclocked "reference" card to stock levels.2. Overclock the competing AMD card by a comparable amount (or use a factory overclocked AMD card as the reference point)3. Publish a review using a card that runs at reference clocks, and then afterwards publish a separate review for the overclocked card.4. Overclock both cards to their maximum stable levels, and use that as the comparison point.

Come on now, this is supposed to be Anandtech. It shouldn't be up to the readers to lecture you about journalistic integrity or the importance of providing proper "apples to apples" comparisons. Using a factory overclocked card to establish a performance baseline for a new series of GPU's is biased, no matter how small and insignificant the overclock may seem. Cut it out.Reply
